Investigation of the effect of different variables on strength of adhesive joints

Abstract

In this article, the tensile strength of different adhesive bonded joints under a tensile load was analyzed numerically. The effects of certain parameters, including the bonding length and bonding ratio, were investigated. For this reason, the epoxy adhesive was used. Joints were prepared with aluminum materials. The stress analyses were employed using the Finite Element Method (FEM). ANSYS (v.14.0.1) FEM tool was utilized to investigate the stress distribution characteristics of aluminum lap joint under tensile loading. Numerical results were found to be quite reasonable. The numerical results show that the influences of variations are very notable when the equivalent stresses are between 18 MPa and 20 MPa.

The investigation of the tensile behaviors of single L‐joint type bonded with adhesive and rivet

“…The meshing in adhesive region was performed in a more sensitive manner by dividing it into small pieces [29]. In order to perform the stress analysis of the adhesive, elements at adhesive region and at the overlapping planes have been prepared with high density and elements of outside parts of adhesive re-gions have been prepared with low density [30]. For this reason, the size of elements in the mesh was reduced until a stable stress value was achieved.…”

Behaviour of Bi-Adhesive in Double-Strap Joint with Embedded Patch Subjected to Bending

“…The adherent and the adhesive were modelled as different areas and joined with each other using merged nodes. The meshing in adhesive region was performed in a more sensitive manner by dividing it into small pieces [6,14,22,23]. In order to perform the stress analysis of the adhesive, elements at adhesive region and at the overlapping planes have been prepared with high density; and elements of outside parts of adhesive regions have been prepared with low density.…”
